AUTO-TIRE.

Application filed February 3, 1916.

To-aZZ lwhom t may concern Be it known that I, EDWARD A. ILUG, a citizen of the United States, residing at Erie, in the county oi' Erie and State ot' Pennsylvania, have invented a new and useful'Auto-Tire, of which the following is a specification.

The device forming the subject matter of this application is a vehicle tire, and one object ot the present invention is to provide novel means for supporting the tread portion ot the tire yieldingly and adjustably, and for causing the longitudinal edges ot the tire to coact with the rim.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without f leparting from the spirit of the invention.

In the accompanying drawing: Figure 1 shows in longitudinal section, a wheel rim and tire embodying the present invention; Fig. 2 is a cross section of the structllre shown in Fig. 1.

Inv carrying out the present invention there is provided a rim 1 ordinarily but not necessarily fashioned from wood. The rim 1 is equipped with circumferential spaced passages 2 opening at their inner ends into enlarged recesses 3. Any suitable means may be provided for assembling the tire, hereinafter described, with the rim 1, but in the present instance, the rim is equipped with clencher flanges 11 adapted to coact with clencherbeads 12 on the tire.

The tire includes a canvas body 5, a rubber fiber tread 6, rubber side strips 7 secured to the tread 6 and to the body 5, and a rubber inner strip 8 secured to the body 5, the strip S-being of considerable thickness adj acent the tread of the tire,y and tapering toward its side edges as shown at 9. Generally considered, however, the tire may be made from any desired materials. In the inner face of the strip 8, circularseats 10 are formed, the outer walls of the seats pref- Speccaton of Letters Patent.

era'bly being convexed outwardly, as clearly shown 'in Fig. 2. A sectional metal retaining .strlp 11 which is trough-shaped in cross section bears against the beads 12 of the tire to hold the same engaged with the flanges t, the strip 11 abutting along its longitudinal center against the outer face of the rim 1. i

'.Ihe invention comprises a plurality of adjusting members each embodying a neck 14C rotatable in the passage 2 of the rim 1 and threaded into the retaining strip 11, each adjusting member including a head 15 mounted to rotate in the recess 3 of the rim 1, the head' 15 of the adjusting members being provided, if desired, with openings 16 adapted to receive a spanner Wrench wherei the reduced portion of the opening being indicated at 19.

Mounted to slide in the reduced portion 19 of the opening in each adjusting member 1s a support 20, ordinarily in the form of a rigid rod which is circular in cross section, the support 20 embodying a head 21 abutting against the inner strip 8 of the tire within the contour of the seat 10 therein. A compression spring surrounds each support 2K0, the outer end of the spring abutting against the head 21. The inner end of each spring ,22 is received within the enlarged portion of the opening 17 in the adjusting member and abuts against the shoulder 18. In practical operation, when the adjust` ing members are rotated, the adjusting members will be advanced, because they are threaded into the strip 11. llhen the adjusting members thus are advanced, the springs 22 will be compressed. At the same time, the retaining strip 11 will be retracted and will be caused to bind tightly against the beads 12 yand to bind against the rim 1 owing to the function exercised by the heads 15 of the adjusting members.

It is to be observed that the inner end of the support 20is accessible through the opening 19 in the adjusting member 14h15, whereby the support may be moved outwardly to relieve the compressiveet'fort of the spring 22 on the shoulder 18 of the adjusting member. Because this operation is possible, the adjusting member may be unroo screwed more readily than would be possible otherwise. Y

Having thus described the invention, what is claimed is .In a device of the class described, a rim; a tire having its longitudinal edges engaged j witli the rim; adjusting members each including, in a one piece structure, a shank movable in the rim, and an enlarged head coasting with the inner portlon of the rim,

- each adjusting member having an opening extended entirely therethrough, the opening tire; and a compression spring surrounding a portiony of each support, the outer end of the spring'abutting against the head, the inner end of the spring being received in ythe large portion of the opening and abut- ,K-.ting against the shoulder; the inner end of the support being accessible through the opening in the adjusting member whereby the support may be moved outwardly to relieve the compressive efort of the spring'on the shoulder, thereby facilitating an unscrewing of the adjusting member.

In testimony that I claim the foregoing as my own, I have hereto aiXed my signature,-

in the presence of two witnesses.
